=Press Opinions.=

"This interesting volume has been kept from the pencil of the modern editor and reprinted in its entirety by the enterprising publishers of The Pottery Gazette and other trade journals.... There is an excellent historical sketch of the origin and progress of the art of pottery which shows the intimate knowledge of classical as well as (the then) modern scientific literature possessed by the late Dr. Shaw; even the etymology of many of the Staffordshire place-names is given."—Glasgow Herald.

"The historical sketch of the origin and progress of pottery is very interesting and instructive. The science of mixing is a problem of great importance, and the query how the natural products, alumina and silica can be compounded to form the best wares may be solved by the aid of chemistry instead of by guesses, as was formerly the case. This portion of the book may be most suggestive to the manufacturer, as also the chapters devoted to the subject of glazes, glasses and colours."—Birmingham Post.

"Messrs. Scott, Greenwood & Co. are doing their best to place before the pottery trades some really good books, likely to aid the Staffordshire manufacturers, and their spirited enterprise is worthy of encouragement, for the utility of technical literature bearing upon the practical side of potting goes without saying.... They are to be congratulated on their enterprise in republishing it, and we can only hope that they will meet with the support they deserve. It seems to be a volume that is worth looking through by both manufacturers and operatives alike, and all local institutions, at any rate, should secure copies."—Staffordshire Sentinel.

=Press Opinions.=

"The book is one that is of value to every one connected with the colouring of paper."—Paper Trade Journal.

"The great feature of the volume is undoubtedly the series of actual patterns of dyed papers, 157 in all—twelve of which, made in England, have been added to the original German series. Detailed formulae are given for the preparation of the pulp for each, and the tints of the samples practically form a key, by means of which the accuracy of the student's or practitioner's experiments can be tested.... On the whole the publication is one of distinct importance to the trade, and will no doubt speedily become a standard work of reference amongst papermakers, both in the 'lab.' and the office, as well as being an excellent text-book for the use of students in the increasing number of technical institutes in which papermaking is taught."—World's Paper Trade Review.

=Press Opinions.=

"Should prove of great service to all who are either engaged in or interested in the art of enamelling."—Jewellers and Watchmakers' Trade Advertiser.

"I must inform you that this is the best book ever I have come across on enamels, and it is worth double its cost."—J. MINCHIN, Jr., Porto, Portugal, 22nd July, 1900.

"This is a very useful and thoroughly practical treatise, and deals with every branch of the enameller's art. The manufacture of enamels of various colours and the methods of their application are described in detail. Besides the commoner enamelling processes, some of the more important special branches of the business, such as cloisonne work are dealt with. The work is well got up, and the illustrations of apparatus are well executed. The translator is evidently a man well acquainted both with the German language and the subject-matter of the book."—Invention.

"This is a most welcome volume, and one for which we have long waited in this country. For years we have been teaching design applied to enamelling as well as to several other crafts, but we have not risen to the scientific side of the question. Here is a handbook dealing with the composition and making of enamels for application to metals for the most part, but also for other allied purposes. It is written in a thoroughly practical way , and its author—Paul Randau—has made its subject a very particular study. The almost all things which come from the German chemical expert, is a model of good workmanship and arrangement, and no one who is in search of a handbook to enamelling, whether he is a craftsman producing his beautiful translucent colours on gold, silver and copper, or the hollow-ware manufacturer making enamelled saucepans and kettles, can wish for a more useful practical manual."—Birmingham Gazette.

=Press Opinions.=

"It would be well if our English manufacturers would avail themselves of this important addition to the extensive list of German publications which, by the spread of technical information, contribute in no small degree to the success, and sometimes to the supremacy, of Germany in almost every branch of textile manufacture."—Manchester Courier.

"This is probably the most exhaustive book published in English on the subject dealt with.... We have great confidence in recommending the purchase of this book by all manufacturers of textile goods of whatever kind, and are convinced that the concise and direct way in which it is written, which has been admirably conserved by the translator, renders it peculiarly adapted for the use of English readers."—Textile Recorder.

"A careful study of this book enables one to say with certainty that it is a standard work on the subject. Its importance is enhanced greatly by the probability that we have here, for the first time in our own language, in one volume, a full, accurate, and detailed account, by a practical expert, of the best technical methods for the testing of textile materials, whether in the raw state or in the more or less finished product."—Glasgow Herald.

"The author has endeavoured to collect and arrange in systematic form for the first time all the data relating to both physical and chemical tests as used throughout the whole of the textile industry, so that not only the commercial and textile chemist, who has frequently to reply to questions on these matters, but also the practical manufacturer of textiles and his subordinates, whether in spinning, weaving, dyeing, and finishing, are catered for.... The book is profusely illustrated, and the subjects of these illustrations are clearly described."—Textile Manufacturer.

=Press Opinions.=

"A long-felt want in the weaving industry has been supplied by the issue of a cheap volume dealing with the subject."—Belfast Evening Telegraph.

"The work has been clearly translated from the German and published with suitable illustrations.... The author has dealt very practically with the subject."—Bradford Daily Telegraph.

"The book, which contains a number of useful coloured diagrams, should prove invaluable to the student, and its handy form will enable it to become a companion more than some cumbrous work." —Cotton Factory Times.

"The book has been prepared with great care, and is most usefully illustrated. It is a capital text-book for use in the weaving schools or for self-instruction, while all engaged in the weaving industry will find its suggestions helpful."—Northern Daily Telegraph.

"The various systems are treated in a careful manner; also the different looms and their manufacture, as well as the whole processes of the work. Yarn numbering according to various systems, with conversion tables and numerous coloured diagrams, materially assist to a clear comprehension of the subject."—Northern Whig.

"The 'inside' managers of our textile mills in which the work is complex or greatly varied, and where yarns of different materials are in use, will find this work convenient for reference in case of novelty or difficulty. We may also say the same in relation to the textile student. Its description of the parts of the loom and their functions will be of use to the latter, being of the most elementary kind."—Textile Mercury.

"The author attempts to fill a gap in weaving literature caused by the neglect of many obscure points connected with the industry. A short review is given of the power-loom as a whole, followed by a description of the different parts of the machinery with their advantages and defects.... The book is severely technical, but must on that account be very valuable to the pupil who is determined to master this industrial art."—Cheshire County News.

"It is clear and concise, and gives just that knowledge in quality and amount which any student of the weaving industry ought to consider as a minimum necessary for his thorough comprehension of his future profession. The handiness and variety of the information comprised in Section III., dealing with the numbering and reeling of yarns employed in the various systems in different countries, struck us as particularly useful."—North British Daily Mail.

"This work brings before weavers who are actually engaged in the various branches of fabrics, as well as the technical student, the different parts of the general run of power-looms in such a manner that the parts of the loom and their bearing to each other can be readily understood.... The work should prove of much value, as it is in every sense practical, and is put before the reader in such a clear manner that it can be easily understood."—Textile Industries.

"The book under notice is intended as an instructor to those engaged in power-loom weaving, and, judging by its compilation, the author is a thorough master of the craft. It is not overloaded with details, and he manages to compress in a book of some 150 pages all that one can possibly wish to know about the different parts of the machinery, whether of English or foreign make, and for whatever kind of cloth required. A comprehensive summary is also included of the various yarns and methods of numbering them, as well as a few useful hints and a number of coloured diagrams for mandarin weavings. The book is printed in bold, legible type, on good paper, has a copious index, and is well and strongly bound."—Ashton-under-Lyne Herald.

"In dealing with the complicated parts of various classes of power-looms, the writer, who is one of the professors at the Royal Weaving School of Asch, brings to the work a thorough knowledge of the subject, and, what is of great value, he has the gift of communicating his knowledge in a way which is easily understood. The smallest details of loom-setting are entered into, and a full explanation of problems, which are a source of anxiety to many engaged in overlooking, is given. Students will find the work an admirable text-book, and all who are interested in weaving will see in it a valuable addition to the literature on this subject.... The book is in small compass, and is crowded with valuable information."—Bradford Observer.

"The book is worthy the attention of the trade."—Worcester Herald.

"The treatise is arranged with great care, and follows the processes described in a manner at once clear and convincing."—Glasgow Record.

"A most useful manual dealing in an intelligible and interesting manner with the colour printing of carpet yarns."—Kidderminster Times.

"An eminent expert himself, the author has evidently strained every effort in order to make his work the standard guide of its class."—Leicester Post.

"The book, which is admirably printed and illustrated, should fulfil the need of a practical guide in the colour printing of carpet yarns.—Nottingham Express.

"The subject is very exhaustively treated in all its branches.... The work, which is very well illustrated with designs, machines, and wool fibres, will be a useful addition to our textile literature."—Northern Whig.

"It gives an account of its subject which is both valuable and instructive in itself, and likely to be all the more welcome because books dealing with textile fabrics usually have little or nothing to say about this way of decorating them."—Scotsman.

"The work shows a thorough grasp of the leading characteristics as well as the minutiae of the industry, and gives a lucid description of its chief departments.... As a text-book in technical schools where this branch of industrial education is taught, the book is valuable, or it may be perused with pleasure as well as profit by any one having an interest in textile industries."—Dundee Courier.

"The book bears every mark of an extensive practical knowledge of the subject in all its bearings, and supplies a real want in technical literature. Chapters IX. and X., on the science of colour mixing and colour matching respectively, are especially good, and we do not remember to have seen the bearing of various kinds of light, and of the changes from one kind of light to another on the work of the colourist, so well treated elsewhere."—Dyer and Calico Printer.

"It is thoroughly practical, and contains much information which has not hitherto appeared in book form. It is pleasing to note that the practical part is not crowded out with purely 'practical recipes'. A few typical examples are given, and the rest is left to the common sense and judgment of the printer or works' chemist. Another pleasing feature is the accounts given here and there of the author's own researches on the subject. The work will be of interest to printers of wool generally, and to those engaged in the dyeing of this fibre."—Journal of the Society of Dyers and Colourists.
